Topic: Corrupted data

I downloaded Advance wars today and after I did, I saw I also had updated Nes remix and some corrupted data. All it said was that it was an error and was corrupted and I should delete it. I did.
But is it common? I havnt done anything wrong, its just annoy me that this poped up

Edit: its probaly nothing important. Im very carefull to follow onscreen instructions while downloading things. Probaly just somthing free demo thing they downloads for me sometimes

Do you know what the corrupted data was for? Usually if your internet goes out while downloading or you turn off the system at a wrong time is data corrupted.

Nope, I dont. Probaly nothing important annyway. If it was some update for a software, it can probaly wait. I never turns it completely off if im downloading a game or somthing like that. I delete moste of the free stuff it downloads for me. I have for example no intention to watch youtube on my wii u. Or use something netfeliks or whatever it wase it gave me.
